"Best wishes to Congress president Smt. Sonia Gandhi on her birthday. May Almighty bless her with a long&healthy life," Modi tweeted.

Sonia, who turned 68 today, has decided not to celebrate her birthday in view of terror and Naxal attacks in Jammu and Kashmir and Chhattisgarh respectively.

"In solidarity with the martyred Army and police personnel there, Gandhi has asked Congresspersons not to celebrate her birthday," the party had said in a statement.

This is the first birthday of Gandhi after the last Lok Sabha elections, which saw a virtual rout of Congress nationwide at the hands of BJP.
